Use logcat, or use the various getStatus methods to see what's going on.  File a bug with a bugreport and sample code that results in the problem.

It would be nice to see setInitialDelay() on PeriodicWorkRequest.Builder in the next version, Thanks

Just a "+1" "me too" to add another voice to this... would make so much sense to be able to have setInitialDelay() on PeriodicWorkRequest.Builder

Android must list down the challenges of Periodic Work request  in there documents, I am  tracking Work Manager since it was alpha.Here are the limitations of Priodic Work request:
1. Periodic work request does not support setInitialDelay.
2. Periodic Work request does not support the Chining.

Both of these items are listed in the official documentation for PeriodicWorkRequest: https://developer.android.com/reference/androidx/work/PeriodicWorkRequest

"Periodic work has a minimum interval of 15 minutes and it cannot have an initial delay."
"Periodic work cannot be part of a chain or graph of work."

Still not supported...
I feel that many people need it...would make so much sense to be able to have setInitialDelay() on PeriodicWorkRequest.Builder

Setting a flex period effectively delays a PeriodicWorkRequest.

+1 from me too, with an extra option to limit the number of repeats, for example, run a periodic job daily for 7 days and then stop.

+1 for setInitailDelay() and limitNumberOfFires() for Periodic work request!

What is the best solution for now to setInitailDelay() ?

You can use a PeriodicWorkRequest.Builder with a flex Period as suggested in #13.
This behaviour is documented: https://developer.android.com/reference/androidx/work/PeriodicWorkRequest.Builder#PeriodicWorkRequest.Builder(java.lang.Class%3C?%20extends%20androidx.work.ListenableWorker%3E,%20long,%20java.util.concurrent.TimeUnit,%20long,%20java.util.concurrent.TimeUnit)

The call creates a PeriodicWorkRequest to run periodically once within the flex period of every interval period.

What I mean by setInitailDelay() is the delay before the first run then a fixed periodic delay.

still can't rely on it :(
I calculate millis to midnight and schedule a daily backup with PeriodicWorkRequest (should happen each 24h), and it just won't fire up the Worker.
When I remove setInitialDelay() call, PeriodicWorkRequest - it works!
